They're both GL7P64, so I thought it would work. Some of the codes do work.

Did you test them on emulator though? They don't work there.

The Moon Jump codes don't do anything, even when holding A. Yes, I am using the right game version. Edit: None of the codes in the first section work. The Beta/Test Level codes work fine. Edit 2: The test levels with "test" in their name don't load properly. Instead of loading into the act...

I downloaded that program, aligned the ISO, extracted the root with GCRebuilder, did the file replacements, opened the root, saved it, but clicking Rebuild still gives me the same error. I should mention that I've rebuilt over a dozen ISO's for other games and they all worked perfectly and gave no e...

I don't see a download link anywhere, not for that tool.

Still no email. RIP

I sent the creator an email a day or two ago, still no response. I'd be surprised if he ever did respond.

It's only this ISO, too, all other game I've tested do work with this method and using GCRebuilder 1.1 alone.

I kept the original filenames, I made sure I didn't add any files, some of the replacements are bigger, but doing the Open Root method allows for that.

No, I wasn't using 1.0. I was using 1.1. I downloaded 1.0 from that link you posted but even 1.0 is giving me that same error.

Okay, I extracted everything using GC-Tool, then did the rest in GCRebuilder. GCRebuilder is still giving me the same error. It shouldn't be this hard.

I'm trying to use this GC-Tool program, however I don't see an option to open the root, and right clicking any file and selecting "replace" brings up the error "Error: This is not a file!". Seems like this tool doesn't work either.

Download it where?

Net Framework is completely up-to-date. I don't know what GC-Tool or TOC are.

I can't reach Step 3 without running into that error though, the error prevemts me from building the ISO.

I tried it with another ISO and Rebuld worked fine. But I need to modify this ISO. To be specific, the game is Lego Star Wars 2. I'm trying to access some test levels by replacing normally playable levels with the test levels.

Okay, I did it again. I opened GCRebuilder, enabled both of those options, THEN did the rest. It's still giving me the same error. If I try and delete any files and then open the root folder, it says "[filename] cannot be found" then doesn't do anything.

I enabled "Modify System Files", but clicking "Rebuild" still causes the "Memory stream is not expandable" error. "Do not use game.toc" is greyed out and can't be selected. Also, the game I'm modifying can be extracted and modified properly. I made a YouTube v...

Larger ISO? If I delete any files and try to open the root, GCRebuilder will say there's missing files and will refuse to open anything. I'm fine with a larger ISO, I'm emulating it, however I don't see an "Allow Larger ISO Creation" option anywhere. Or I'm completely misunderstanding what...

That's actually much easier than I was expecting. While we're on the topic of GCRebuilder, I can't seem to replace the banner. Even if the file is the exact same size, it says it's too big. Edit: New issue - I followed that GCRebuilder tutorial, however when I click "Rebuild", it brings up...

I use emulation, so burning things to discs isn't an issue for me. I just need the modified ISO. I'm looking at GCRebuiler while typing this, it's the tool I tried using. I don't see an option to create a new ISO, only extract individual files and replace files. I'm using Version 1,1, which is the n...

I originally posted this on Reddit, but was directed here as this might be a better place to talk about this. I'm a big fan of looking through the file structures of GameCube games and finding unused content or developer test levels and putting them into the game using file replacement tools. There ...
